Study On The Influence On The Polarized Reflection By Loessial Dense Degree

The smooth degree of soil surface can influence directly the degree of polarization. The smooth degree of soil surface will be influenced by keeping the loess's cubage unchanged and changing the loessial dense degree by loessial weight, which can influence polarized reflection. This paper analyzed the reflection spectrum of loess on different granule diameters and irradiant angles. We found that the influence of loessial dense degree on its polarized reflection changed along with loess's moisture content and angle of incidence. It suggested that in the quantitative study of polarized reflection or bidirectional reflection of soils, the influence of soil's dense degree should be considered.
